Abstract : Reactant-solvent interactions are of prime importance to both the kinetics and thermodynamics of electrode processes. Since electrochemical reactions inevitably occur within the interfacial region, it is desirable to gain information on the nature of reactant solvation at the electrode surface as well as in bulk solution. We have demonstrated that useful information on the latter for simple redox couples can be obtained from the so-called reaction entropy, determined from the temperature dependence of the formal potential, using a nonisothermal cell arrangement.
